The star's doc claimed Michael was infatuated with the daughter of close friend, Mark Lester.

He first met his god-daughter, Harriet, when she was five-years-old, but aged 12 the Thriller singer wanted to wed the girl after he became "fixated" on the pre-teen.

Mr Murray, writing in the Sunday Mirror ahead of the book's release, said:“He wanted me to go with him to visit her father and to discuss plans for ­matrimony while in London, during the This Is It concerts."
